Open spaces in the urban Built Environment (BE) are key places in risk management of SUdden Onset Disasters (SUOD) and their vulnerability is strictly related to the BE characteristics (extrinsic or intrinsic). In literature, several studies identify specific aspects of risk in the BE open spaces, but there is a lack of synthetic or comparative studies in this field.
The results from D1.2.3 allows tracing a clear overview of the current level of knowldege by organizing five macro-areas for classification of BE, introduced in D1.1.1 and D1.1.2, and identify specific factors involved in the seismic risk of open spaces in BE.
